Description

Super absorbent polymer hydrogel shredder

The present invention relates to a super absorbent polymer hydrogel shredding apparatus for uniformly shredding a hydrogel.

Super Absorbent Polymer (SAP) is a synthetic polymer material that has the ability to absorb moisture of 500 to 1,000 times its own weight, and each developer has a SAM (Super Absorbency Material), AGM (Absorbent Gel). Material) and so on. Since the above-described superabsorbent resin has begun to be put into practical use as a sanitary tool, nowadays, in addition to hygiene products such as paper diapers for children, soil repair agents for horticultural use, water resistant materials for civil engineering and construction, sheets for seedlings, freshness maintenance agents in the food distribution field, It is widely used as a material for poultice.

As a method of preparing the super absorbent polymer as described above, a method by reverse phase suspension polymerization or a method by aqueous solution polymerization is known. Regarding the reverse phase suspension polymerization, for example, Japanese Patent Publication No. 56-161408, Japanese Patent Publication No. 57-158209, and Japanese Patent Publication No. 57-198714 are disclosed. As a method by aqueous solution polymerization, again, a thermal polymerization method in which the hydrogel polymer is polymerized while breaking and cooling in a kneader having several axes, and photopolymerization in which polymerization and drying are performed simultaneously by irradiating a high-concentration aqueous solution with ultraviolet rays or the like on a belt. The method and the like are known.

The hydrogel or hydrogel polymer obtained through the polymerization reaction as described above is generally pulverized through a drying process and then commercially available as a powdery product. In order to efficiently perform the above drying step, it is important to increase the surface area of the hydrogel polymer as much as possible. Therefore, in order to increase the surface area of the hydrogel polymer before the drying process as possible, a method of increasing the surface area of the hydrogel polymer to be dried by simply pulverizing the polymerized hydrogel polymer through thermal polymerization or photopolymerization can be considered. In order to increase the surface area of the hydrogel polymer as described above, a process of first pulverizing the hydrogel polymer after polymerization has been disclosed.

In the first grinding process of the hydrogel, a chopper is mainly used.

Such a chopper includes a screw for moving the hydrogel, a barrel including a spiral, a cutter blade for cutting the hydrogel, and a perforated plate from which the cut hydrogel is discharged.

In such a conventional chopper, the moving direction of the hydrogel particles injected into the barrel and the screw is horizontal. Therefore, the pressure applied to the hydrogel particles at the position where the perforated plate is disposed is not uniform, and the working pressure at the lower position of the barrel is greater than that at the upper portion, thereby preventing uniform shredding in the perforated plate.

As described above, when the size of the finely divided particles of the hydrous gel is not uniform, non-uniform drying may occur for each particle during the drying process of the hydrous gel, resulting in excessive drying or undrying.

Here, the excessively dried product of the hydrous gel may generate a large amount of fine powder in the manufacturing process of the super absorbent polymer, thereby causing a problem in the manufacturing process. In addition, the undried product of the hydrous gel has a problem in that it is difficult to manufacture a smooth super absorbent polymer in processes such as pulverization or classification as well as the physical properties of the prepared super absorbent polymer.

An embodiment of the present invention is to provide a super absorbent polymer hydrogel shredding device capable of uniform shredding of the hydrogel, thereby improving the manufacturing quality of the super absorbent polymer.
